Paddy and Mick are at a job interview for a labourer by a builder

Paddy goes first and is asked, "If you lost an eye, what would you be?"
He answers, "Half blind."
Then he was asked, "What would you be if you lost both eyes?"
He answers, "Blind."...
Builder says, "Great, you got the job - send Mick in."
Mick over heard the interview and thinks, "Great, I'll just give the same answers."
The builder asks, "If you lost an ear, what would you be?"
Mick says, "Half blind."
Then was asked, "What about if you lost both ears?"
Mick says, "Blind."
The builder, a bit puzzled, asked, "How would that be?"
Mick says, "My hat would slip down!!..
